Said screw engages in a tappedopeningiin'the forwardly extending arm 20 of an angular bracket which furthercomprises a lateral arm 21v secured by screws 22' to the slide .bar 6;and the head of saidscrew frictionally engages the extension :17. Thebracket 20, 21 is thus rigidly secured to the platen frame by the screws22 and the circular supporting plate 16 is rigidly and adjustablysecuredby the screw and slot connection 18, 19-to said bracket, thus providingarigid support for-the left-hand platen section at its inner orright-hand end. The plate 16 is of substantially the same diameter asthe platen section and its outer face or periphery conforms to theplaten surface.

The left-hand platen section abuts against the left-handTace of theplate 16 while A pin 15"pass, v i

eshorizontal open-mouthedi-slot18whichrei contiguous to the right-handface of said plate is the right-hand platen section which comprises acore23 and a sheath 24. Secured to the left end of the core by woodscrews 25 is a platen head 26 which is overlapped by the sheath 24 andis formed with a depressed or recessed portion 27 which fits withinthe-core 23 and also provides room for the hub 13. The platen head 26bears on a long sleeve or collar 28 which surrounds the axle 9. Thelefthand end of this sleeve 28 abuts againstthe hub Y13;-

and said sleeve extends through the righthand platen section and throughthe end bar 8, being secured in rigid relationship with said end bar bya screw 29 which, however, does not engage with the axle 9, said axlebeing free to turn in the sleeve 28 which is rigidly secured to theplaten frame.

"Wood screws 30 secure a platen head 31 to the right-hand end of theright-hand platen section, said platen head being provided @section by ascrew 35 which passes through the hub 32 and engages a tapped opening inthe hub 33. The gear wheel 3 l-is at the. left of the end bar 8.

.- bar and contiguous to the end of the sleeve 28 is a second gear wheel36 provided with i a hub 37 which receives a set'screw 38 which abutsagainst the axle 9 and rigidly secures the geanwheel -36 thereto. Theright-hand end portion of the axle 9 beyond the hub 3'? i has secured toit a finger wheel 39 of ordi naryconstruction by which the axle 9, and

under normal conditions, the left-hand platen section only, may beturned or rotated for line spacing or other purposes.

The gear wheels 3% and 36 have the same number of teeth, which numbermay equal that of the teeth of the line spacing ratchet wheel (notshown). r

The construction is such that the gearwheel 3% is constantly connectedto the right-hand platen section while the gear wheel 36 is constantlyconnected to the lefthand platen section These two platen sections arenormally independent but means are provided for connecting the twoplaten sections so that they will turn. together, said means beingmovable independently of the two platen sections and into and out ofengagement with the two gear wheels or connecting devices 34; and Saidmeans in the present instance comprise an elongated pinion 40 arrangedat the rear, lower side of the gear wheels 34: and 36 and of sufficientlength to engage with both gear wheels but normally out of meshtherewith. The pinion 40 is mounted to rotate on the body portion-of ashouldered screw 41, the lefthand end' of which is supported on a mem'ber 42, the right-hand end of said screw being supported tin an angularextension 43 on said member. The right-hand end portion of the screw l1.isreduced and threaded and receives a locking not a l (Fig. 3). Themember 42 is provided with a hub 45 which bears on a rod 46, this rodpreferably being the rod or rock shaft which operates to release theusual feed rollersof the machine," Said feed rollers arediagrammatically illustrated in Fig. 1 wherein theyare numbered 47 and47 and they cooperate with other devlaterally cit-set into thevicesincl'uding the paper table 48 to guide 60 and control the paper.The member 42 has an n ward and forward extension or arm 49 w ichterminates in a tooth 50 which is plane of the gear wheel 34 with theteeth whereof the tooth 50 normally engages as shown in Fig-'1'.

Outside said end I mally vertically d sposed and is adapted to LopeaseThe toothed arin or device 49, 50 cooperateswith said teeth to lock thegear wheel 34: and the right-hand platen section normally againstrotation. When disengaged, as is normally the case, the pinion 40 isprevented fronrturning accidentally by a spring detent '51, said detentbeing provided at its upper end with a slot 52 which receives a screw.53 which thus 'adjustably secures the The rear edge 540i the member Qis nor cooperate with anactuating device or bar 55 arranged above -thetop'plate 2 and secured thereto by a screw 56. Said bar 55 extendsrightward beyond the top plate and its overhanging portion is secured bya screw 57 to a bracket 58 ri'gitllyanounted on the lower track-way l.The right-hand end 'of the bar 55 is curved or bent rearwardas indicatedat 59 so as to intersect the pathway ,of the edge 54: and-this curvedportion is so located that as the right-handplaten section approachesthe printing field of the types'the edge 54: will engage with the curveor cam 59 with the resultfthat as the leftward movement of the platencontinues, the

edge 54 will be forced forward, swinging the member 42 on its pivotalaxis 4:6. This swinging movement disengages the tooth 50, unlocking theright-hand platen section which previously had been prevented fromturning during line spacing operations of the left-hand platen section.Also, the swinging movement carries the pinion 40 into mesh with thegear wheels 34 and 36, 1 thereby connecting said gear wheels and throughthem the two platen sections. The

pinion partiallyengages' before the tooth 5O entirely disengages. Thenormal positions of the parts are shown iniFlg. l, and the operatedposition just described is shown in Fig. 2. It will be apparent thatduring additional further leftward movement or the platen the cam bar 55will operate to maintain the pinion engaged or operative as in Fig. 2 sothat a turning or line spacing movementcommunicated to the left-handplaten section will be participated in by the right-hand platen section,the two platen sections turning as a single platen. The connectionbetween the two platen sections for this purpose is automaticallybrought about as soon as the right-hand platen section enters theprinting field and such connection continues during the entire time thatthe right-hand platen section remains in position to cooperate with thetypes. It will be understood that the present construction,

.nnlike that in my prior application aforesaid, permits of unlimitedsimultaneous rotation of the two platen sections while they areconneotedthr'oughthe pinion it).

When the platens are restored toward the 1 right far enough to disengagethe edge 54:

' the said platen they may be from the cam bar, the connecting andlocking device 42-, 49 will be forcedback' to the normal position by acoiled restoring spring (30, said restoring spring being wound aroundthe hub 45 and having one endsecured to the arm 49, the opposite endbeing hooked around a screw 61 wliichsecures a limiting collar 62 to therock shaft ii collar 62 cooperates with a collar 63 at the opposite sideof the member 462, d5, 49 to prevent endwise movement of the said memberon the rock shaft while permitting the member to rotate relatively tosaid shaft.

My present invention is particularly useful in connection withcommercial billing work wherein a series of bills or invoices are beingWritten and a record is being kept of certain data from each bill. Forexample, the bill sheets may be written on the left-hand platen sectionwhile the totals 01 each bill may be written on a continuous sheet ortally strip which is fed around the right-hand platen section. It willbe understood that the usual or suitable paper controlling devices, suchas the papertable 48 and feed rollers 47 and 47 may be employed inconnection with the lefthand platen section; while with the right-handplaten section paper supporting, feeding and controlling devices of thecharacter described and claimed in my application aforesaid may be used.

From What has been said it will be understood that the right-hand platensection is held locked against rotation during the writing and linespacing of the work sheet on the left-hand platen section but whenright-hand platen section has been brought opposite the printing pointitwill be unlocked and automatically connected with the left-hand platensection so that the two may be turned or rotated togethersimultaneously.

Various changes may be made without departing from the spirit and scopeof my invention.

What I claim as new and by Letters Patent, is:

1. In a typewriting machine, the combination of a plurality of platensections; and means operating automatically to couple sections together,said means including a coupling device normally disconnected from saidplaten sections but operative to couple said platen sections so thatthey may be turned together to an unlimited extent 2.
